I liked Telegram at the start but they started doing crypto (I believe Signal does this too) and when I realize that default chat is not E2E encrypted (has to be secret chat) yet they advertise it as such. I also don’t like that you get greeted by paid features in different parts of the app (picking emoji and stickers). I’m fine with Telegram Premium but I hope they just hide the paid features rather than asking you to pay for the features across the app. Telegram’s UI/UX is way better than Signal and other messaging app which I like. Also, feature-wise they are ahead of the competition (even without premium). The fact that it’s one of the major communication outlet during Ukraine war is another issue plus. Privacy-wise, there are better options out there (Signal, Sessions, Briar, SimpleX (a new one), Element/Matrix). I still use it but not as much.
